Lavar Edwards' time in Oakland was brief. He was claimed off waivers from the Dallas Cowboys on September 7. Now four days later, he was waived by the Raiders to make room for the signing of Aldon Smith which is now official.
Edwards' addition had made the Raiders very deep at the defensive end spot. The former 5th round pick (142 overall) by the Tennessee Titans in the 2013 draft spent one season in Tennessee appearing in 7 games with one start. Following that season he was traded to the Cowboys for a 7th round pick. He appeared in four games last season for the Cowboys.
With the opportunity to sign a former All Pro pass rusher in Aldon Smith, the Raiders weighed the risk and added him on a 1-year deal. Had they not cut a DE in the process, they would have had six of them when four is more typical.
Smith is eligible to play this Sunday at this moment as the league decides whether to suspend him for his DUI arrest this offseason. Should he be suspended, the Raiders still have four defensive ends on the roster in Khalil Mack, Justin Tuck, Mario Edwards Jr, and Denico Autry.
